Eunotia nymanniana

 

Eunotia orthohedra

LM scalebar = 10 µm = 80 pixels.



Observations

Contributor: Paula Furey - March 2011
Length Range: 50-54 µm
Width Range: 3.3-3.8 µm
Striae in 10 µm: 13-14 in the center valve, 18-20 at the ends, areolae 40-44

Description

The ventral margin is concave. The dorsal margin is convex and lacks a shoulder. The apices are slightly narrowed and rounded. The helictoglossae are not visible in the LM. The striae are distinctly oblique on the valve mantle and in the valve center, and become radiate near the apices.

Autecology Discussion

To date, E. obliquestriata has been found epiphytic on bryophytes in a soil seep at a rock outcrop at the bottom of a dry water way along the Long Hungry Ridge Trail off the 20 – Mile Creek Trail in the Great Smoky Mountains National Park.
